The plastic rod is made of insulator (plastic), so it does not allow charges moving from one sphere to another. This means that all the electrons given to sphere A will remain on sphere A.
The number of electrons initially given to sphere A is
, and since the charge of 1 electron is
, the net charge left on sphere A after the removal of the rod will be
Supplementary angles add up to 180°.
If one is 40°, then the other is (180° - 40°) = 140° .
None of those choices describes a plane.
Choice 'C' is the only example of a plane.
Answer:
The horizontal displacement is 
Explanation:
From the question we are told that
The angle at which the string is maintained is 
The length of string reeled in is 
Using the SOHCAHTOA formula
We have that the hypotenuse(Hyp) is l = 152
Hence the horizontal displacement of the kite which is the Adjacent(Adj) can be evaluated as
substituting values
=>
The independent variables would be time and he dependent variables would be the distance traveled. Time is always independent because it is not reliant on something else when something happens over a period of time.
Velocity - v =0 m/s,
initial velocity - v(0)= 40 m/s
a - acceleration,
time - t = 12 s.
v=v(0) - at
0 = 40m/s - a*12s
12a = 40
a = 3.3 m/s²
